Description
SUITIT HH-5636 is a two-component room-temperature vulcanized silicone gel with thermal conductivity of 2 W/m·k, engineered for potting electronic components with strict flame retardant requirements. It features convenient 1:1 mixing ratio by weight and volume, low viscosity for easy pouring and flow filling of complex structures.
Features
- Easy 1:1 mixing ratio by weight and volume, compatible with automatic dispensing equipment and manual operation
- Good fluidity to fill intricate component structures
- Heating significantly shortens full curing time
- High elasticity after curing, no brittleness or powder shedding
- Wide temperature resistance range: -50 ~ 200℃
- Flame retardant rating meets UL94 V-0 standard
